Back in June I bought one for myself and and another for Joe Real at Bonita Creek Nursery, east of San Diego. They were all supplied by Brokaw Nursery, FYI. I believe Four Winds plans to have them available before long and they do mail orders.

Here's my latest research.
Tango will be available for the June 2007 UCR Budwood cut.
Rafa: Since Tango is so new I believe you will have a hard time getting a budwood of that tree but Joe Real has got one recently because of his affiliation with Davis University and successfully graftied them to his other citrus plants. But it is going to take time to cut a budwood from his grafts.
For those of you who are wondering what is a tango mandarin:
As per Joe Real input:

Claims:
1. A new and distinct variety of mandarin hybrid tree having the characteristics essentially as described and illustrated herein.
Description:


LATIN NAME OF THE GENUS AND SPECIES

[0001] The mandarin cultivar of this invention is botanically identified as Citrus reticulata.

VARIETY DENOMINATION

[0002] The variety denomination is `Tango`.

BACKGROUND OF THE INVENTION

[0003] `Tango` is a mandarin selection developed at the University of California Riverside from an irradiated bud of the diploid mandarin cultivar `W. Murcott`, a mid-late season maturing variety. The pedigree of `W. Murcott` mandarin is unknown but is believed to be a seedling selection from a `Murcott` Tangor tree produced in an open-pollinated field. The cultivar `W. Murcott` from which `Tango` was derived may be identical to a mandarin cultivar known as `Afourer` and also as `Nadorcott`. The name `W. Murcott` was assigned to a mandarin cultivar which was imported into the United States as buds in 1985 from Morocco. `Afourer` and `Nadorcott` are known to have originated in Morocco. `Nadorcott` was patented in the United States in 1997 under U.S. Plant Pat. No. 10,480 (filed in January 1997). `W. Murcott` was first commercially available in California in 1992-1993.

[0004] `Tango` originated as a single plant and was asexually reproduced by grafting of budwood onto rootstocks. `Tango` was selected and propagated as follows. Irradiation of `W. Murcott` budwood taken from registered trees in the Foundation Block at the University of California Lindcove Research and Extension Center (LREC), Lindcove, Calif. was accomplished in June, 1995 at Riverside using 50 Gray units of gamma irradiation from a Cobalt-60 irradiation source. Buds from this irradiation were propagated onto various rootstocks in the greenhouse at Riverside where they were grown to field-plantable-sized trees. These trees were planted in June 1996 at Riverside. Fruit production and evaluation began in 1998. One tree from this irradiated population (propagated on `C32` citrange rootstock) distinguished itself from the others in having fruit that had very low seed counts with excellent fruit quality and normal fruit production characteristics in comparison to the original `W. Murcott` cultivar. After two seasons of fruiting, this tree (now named `Tango`), was selected for further trials in 1999 and in January 2000 buds were taken and propagated onto `Carrizo` and C35 citrange rootstock. Budwood was also sent to the University of California Citrus Clonal Protection Program (CCPP) in April 2000 for evaluation of disease status and elimination of viruses and other pathogens as needed.

[0005] Twenty trees were planted at Riverside in June 2001. Fruit production on these 20 trees commenced in 2003. In October 2001 the Citrus Clonal Protection Program sent two trees of `Tango`, which had been produced from budwood which CCPP had tested and certified as tristeza-free, to the University of California Lindcove Research and Extension Center where they were planted in the citrus breeding block. Further propagations from the original selection tree in 2001 were made at Riverside and in June 2002 twenty trees were planted at the University of California South Coast Research and Extension Center (SCREC) in Irvine, Calif., and 15 trees were planted at Santa Paula, Calif.

[0006] Fruit production of these propagated trees (at LREC, SCREC and Santa Paula) commenced in 2003 (a few trees at each site) and 2004 (all trees at all sites). In July 2002 budwood was taken from the LREC trees and topworked onto a navel orange/`Carrizo` citrange tree at LREC. In September 2002 eighteen trees, produced from CCPP budwood were planted at Arvin Calif. In August 2003 thirty-six additional trees were propagated at LREC from budwood taken from the LREC trees and in April 2004, twelve were planted at the University of California Coachella Valley Agricultural Research Station in Thermal, Calif., and in June 2004, twenty-four trees (twelve at each site) were planted at two sites, LREC and Woodlake, Calif. All trials were propagated on `Carrizo` and `C35` citrange rootstocks.

BRIEF SUMMARY OF THE INVENTION

[0007] The present invention provides a novel mandarin variety having the characteristics described and illustrated herein. The variety, `Tango`, is a mandarin selection developed at the University of California Riverside from an irradiated bud of the diploid mandarin cultivar `W. Murcott`, a mid-late season maturing variety. `Tango` combines mid to late season maturity, moderately large fruit size, very smooth rind texture with a deep orange color, and a rich, sweet flavor. It further distinguishes itself by being very low seeded (<1 seed/fruit) and very easy to peel.

[0008] Mid to late season maturing mandarin cultivars in production include `W. Murcott` mandarin (the original cultivar from which `Tango` was derived), `Murcott` Tangor, `Fortune` mandarin, `Ortanique` mandarin, `Temple` Tangor, late-maturing Clementina selections including `Hernandina` and `Nour`, `Dancy` mandarin and `Minneola` tangelo. All of these cultivars will be seedy if grown in the presence of a pollenizer. Some, including the Clementina selections, `Fortune`, `Ortanique`, and `Page` mandarins will have few seeds if no pollenizer is present. Recently released mid to late season cultivars that are very low-seeded include `Gold Nugget` (unpatented), `TDE2` mandarin hybrid (Shasta Gold.RTM.) having U.S. Plant Pat. No. 15,461, `TDE3` mandarin hybrid (Tahoe Gold.RTM.) having U.S. Plant Pat. No. 15,703, and `TDE4` mandarin hybrid (Yosemite Gold.RTM.), having U.S. Publication No. 2003/0237120. `Tango` differs from these cultivars in having fruit with a smoother rind texture that are easier to peel. Trees of `Tango` show less alternate bearing than these cultivars. Additional differences (summarized in Table 6) distinguish it from each of these cultivars.

Tango seedless mandarin released for growers

Nov 4, 2006 12:00 PM, By Dan Bryant Freelance Writer dbryant39@comcast.net

Tango, an irradiated, seedless version of the popular W. Murcott (Afourer) mandarin, has been released by the University of California's Citrus Breeding Program.

The mid- to late-season, easy-to-peel W. Murcott has a global reputation for high quality. It has been widely planted in California, particularly near Bakersfield and Madera, during the past decade, with an estimated 2 to 3 million trees planted, more than half of them bearing.

W. Murcott, distinct from the Murcott also known as Honey in Florida and Arizona, has excellent production with little alternate bearing, and, provided it is isolated from other citrus, it produces seedless fruit.

But in California, where isolated commercial citrus orchards are becoming increasingly rare, many W. Murcott groves have developed seedy, lower-value fruit caused by cross-pollination by other mandarins, Valencia oranges, Minneola tangelos, lemons and other citrus.

The Tango was highlighted in a talk on new varieties by Tracy Kahn, principal museum scientist for the Citrus Variety Collection at UC, Riverside, during a recent citrus day at Tulare, Calif.

Kahn, who conducted field evaluations of Tango at Lindcove and Riverside, explained it was developed as a solution to the W. Murcott seed problem. Tango does not have seeds because it does not produce viable pollen.

The new mandarin, developed by geneticists Mikeal Roose and Tim Williams of the Citrus Breeding Program at UC, Riverside, was the most promising of several W. Murcott selections irradiated to induce mutations for reduced seed counts.

Tango was planted in replicated trials at seven locations in the state, including three fruiting trials planted in 2001 and 2002 and four trials planted in 2003 and 2004 that will bear in 2007.

Fruit sampled this year in locations where cross-pollination occurs showed an average of less than 0.2 seeds per fruit, while W. Murcott trees used as a check averaged 8 to 15 seeds per fruit, Kahn said.

At Riverside, Tango matures in late January and holds fruit quality characteristics through April. It has similar tree and fruit traits to W. Murcott except seediness, although this year Tango fruit had lower acidity than W. Murcott.

Fruit size is moderate at about 2.3 inches and 3.2 ounces, shape is oblate with a deep orange color, and the rind is easily peeled. The flesh is also deep orange colored and has a 12 percent to 14 percent Brix when mature.

Tree growth is upright and production begins the second year after planting. Alternate bearing does not appear to be a significant problem.

Since Tango is from mutation breeding, its genetic stability may be an issue, although more than 60 trees propagated from multiple generations of Tango buds have remained true to type.

The Citrus Breeding Program has received patent-pending protection for Tango. Citrus nurseries licensed by the California Department of Food and Agriculture may purchase a license to propagate the new variety.

Among Kahn's 2005 citrus studies are solids-to-acid ratio evaluations of a group of satsuma varieties, mostly foreign in origin, compared to industry standards Frost Owari, Okitsu Wase and Kuna Wase.

China S-2 and China S-9, reported to have cold hardiness, were imported from Hubai Province in China. Aoshima is an Owari selection and one of the leading late-maturing varieties in Japan. China No. 6 and China No. 7 are two other cold hardy varieties from Hubai Province.

Iveriya comes from the former Soviet Republic of Georgia. Silverhill is a nucellar seedling selection of Owari made by W. T. Swingle in about 1908. Xie Shan is a Chinese variety said to ripen extremely early compared to other varieties grown in China.

Miho Wase is a sister nucellar seedling to Okitsu Wase in Japan. Armstrong is from a selection made at the Louisiana State University Research Station. Miyagawa is a limb sport of Zairai selected in Japan in 1923.

Kahn said those meeting the legal maturity standard for solids-to-acid of 6.5:1 at Lindcove as of Oct. 6, 2005, were Okitsu Wase, China S-9, Xie Shan, Miho Wase, Armstrong, and Miyagawa.

Those with soluble solids above 9 at Lindcove were Frost Owar, Okitsu Wase, Kuno Wase, and Miho. Miyagawa was the sole variety with percentage acidity below 1.0 at Lindcove in early October.

Kahn said all the varieties were found to be above the legal maturity solids-to-acid level by Oct. 20, 2005.

Anil Shrestha, IPM weed ecologist at the UC Kearney Agricultural Center at Parlier, urged growers to manage weed pests wisely to help limit the weed seed bank in the soil.

Herbicide resistance is naturally-occurring event in weeds, and almost every herbicide available in California has encountered resistant weeds in other states, he said.

One important practice is not using the same herbicide repeatedly. Eventually, some individuals survive treatments and develop resistance, which multiplies with each generation. Rotating materials having different modes of action will forestall development of resistance.

One tell-tale sign of resistance is when after an application some weeds die while others of the same species do not, Shrestha said.

Growers should not confuse herbicide resistance with a faulty application, which may be caused by improper timing for stage of growth of the targeted weed species, moisture, rate of material, pH of water used in the spray, or calibration of the spray rig.

In a talk on what to expect in winter weather in central California this season, Steve Mendenhall, National Weather Service meteorologist-in-charge at Hanford, forecasted a “weak to moderate El Nino event.”

But, he added, San Joaquin Valley counties, positioned between wet and dry regions of the western state, can expect neither a dry nor a wet year, based on oceanic and atmospheric indicators in the tropical Pacific Ocean.

“So the overall pattern for December through February is for a milder winter, with near normal rainfall and warmer than usual temperatures, but that does not mean we will have no frost,” he said.

Mendenhall said citrus growers can monitor day-to-day forecasts and charts at National Weather Service - NWS Hanford.

I am new to this forum and i would like to know how you go about obtaining a Tango mandarin tree, do I have to be a nursery or citrus grower? Is this regulated? Are there certain states where you cannot send these to? Is this difficult to obtain?

Thanks so much. Any help would be greatly appreciated!

Paula

Richard

Paula,

The Tango has been available in retail nurseries for a few years now. Let us know where you are located and perhaps a member here can help you pinpoint a nursery that has them in stock.

By the way the Tango is not a mandarin. It's parent is the tangor (orange cross mandarin) W. Murcott. Self-pollinated flowers of W. Murcott were irradiated in hopes of producing a seedless variety. Some of the resulting sprouts did develop seedless fruiting trees, and what was deemed the best of these became what we now call Tango. You can read more about it here: Home Fruit Production - Mandarins .

The first and only time I have seen 'Tango' at a retail nursery was at Bonita Creek in San Diego in June 2008. UCR made an "early" release of budwood in June 2007, limiting 12 buds each to commercial nurseries. CCPP - Citrus News

I thought at one time I read that Four Winds was going to have 'Tango' available in 2009, but I have not seen it listed yet. Since they make mail orders and are in northern California (away from quarantine areas), this would be convenient for many hobby growers.

Edit: The trees that were at Bonita Creek were grown by the wholesale nursery Brokaw Nursery so other retail nurseries buying stock from them may also have 'Tango'.

I ordered 30 rootstock from TreeSource a couple of years ago. After a month of not hearing anything, they told me they'd ship them when and if they had the time. I believe that the SCV CRFG chapter (or maybe it was Joe?) organized a group purchase at one point and even then they did not fill orders for many of the requests. I honestly don't think that TreeSource would be a reliable source for hobbyists but would be good if you wanted a commercial planting. Maybe someone here has had a better experience.

Four Winds does list it as one of their future offerings and does have pretty good customer service, from what I've heard. Complete List of Four Winds Dwarf Citrus Varieties

I will second that endorsement of Four Winds Growers. I've ordered from them three times and plant to do it again.

I do wish the Four Winds would indicate what rootstock is used. I'm not sure if they use mostly Flying Dragon or not, but they do specialize in dwarf citrus.

I e-mailed them a rootstock question today for etrog since there are some limitations on it being grafted for kosher requirements. A Jewish friend was suggesting I try to explore this market.

Personally, I wouldn't want Etrog on a dwarfing rootstock -- especially in a cooler winter climate. I would be satisfied with Etrog on a seedling of itself or a Citron-cultivar rootstock. If you want to save some shipping charges, I can check with the sources here and bring you one later this spring when I travel to Davis.
